There have been few build-ups to the Jukskei derby between the Bulls and Lions in recent times that have drawn as much anticipation as the imminent contest between the two sides at Ellis Park this weekend.

Tensions within the International Cricket Council (ICC) took a nasty turn this week with its president Mustafa Kamal threatening to expose "mischievious" deeds by some of the cricket governing body’s officials.

The 39-year-old actress first started dating the 'Blurred Lines' hitmaker, whom she officially divorced last month, when she was just 14 years old and she believes she's been forced to grow up since ending their nine-year marriage in 2014.

"The alleged murder is disputed in the strongest terms," the family and In-Site Athlete Management said in a statement issued by a public relations company in London.

"These are now live and active legal proceedings, which must be allowed to take their course through the process of proper investigation by the police, evidence-gathering, and through the local South African judicial system."

Pistorius was formally charged on Friday with the murder of Steenkamp.

The celebrity paralympian would spend the weekend in jail after his bail application was postponed by the Pretoria Magistrate's Court to Tuesday.

He was arrested on Thursday after Steenkamp, a model, law graduate, and participant in the Tropika Island of Treasure television show, was shot dead in his home.

Pistorius spent Thursday night in jail and will be held at Brooklyn police station in Pretoria until his next court appearance.

His family and In-Site Athlete Management said: "[Oscar] has made it very clear that he would like to send his deepest sympathies to the family of Reeva.

"He would also like to express his thanks through us today for all the messages of support he has received -- but as stated, our thoughts and prayers today should be for Reeva and her family -- regardless of the circumstances of this terrible, terrible tragedy."

They said other statements would be issued as the matter developed.

"In these circumstances I am sure you appreciate it is very difficult to answer any more specific questions."
